WebINTRACRANIAL subdural hematoma is a rare but potentially fatal complication of dural puncture after spinal anesthesia or accidental puncture with a Tuohy needle. The leakage of cerebrospinal fluid may lower intracranial pressure, and caudal movement of the spinal cord and brain stretches and tears dural veins, resulting in subdural bleeding. Cerebrospinal …
WebMar 1, 2000 · A subdural hematoma (SDH) refers to a collection of blood between the dura and the brain. SDHs are three times more frequent in the elderly population.10Most result from bleeding originating from bridging veins, which are prone to injury following acceleration/deceleration movement of the brain. WebMentioning: 5 - The pathophysiology of acute-on-chronic subdural hematoma (ACSDH) is complex and incompletely understood. Evidence to date indicates that the overall process is initiated by rotational force with movement of the brain inside the skull, which exerts tensile strain and rupture of bridging veins, leading in turn to acute hemorrhage in the …
WebJun 27, 2024 · The spinal subdural space is a potential area between the spinal arachnoid mater and the spinal dura mater. Unlike the cranial subdural space, the spinal subdural space does not contain any bridging veins, and thus hemorrhage into this area only occurs in very rare cases 1 . It only contains a minute quantity of CSF and is traversed by … WebFeb 6, 2024 · Pathophysiology Bleeding in a SDH occurs from tearing of the bridging veins that cross from the cortex to the dural venous sinuses, which are vulnerable to deceleration injury. This subsequently leads to accumulation of blood between the dura and arachnoid and results in a gradual rise in intracranial pressure (ICP).
